Adjustable Bed Bottom With Recessed Support for Stable Sit-Up Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing twin beds with adjustable bed bottoms are cumbersome to adjust for a comfortable sit-up position, especially when using a common mattress or mattress cover, as the lower body tends to slip away, and existing solutions do not provide a comfortable position without disturbing the other person in the bed.
Innovation Solution
The twin bed features adjustable bed bottoms with pivotable intermediate sections that create a recess for a person's bottom, allowing for comfortable sit-up positions without disturbing the other person, combined with adjustable headboards that provide resilience and adaptation to the user's position, using mechanisms like pivotable side flaps and flexible supports to maintain mattress stability and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bed bottom is adjusted upwardly to obtain a comfortable sit-up position, then the upper body section moves upward, but the lower body slips away on the mattress and the adjustment is cumbersome with common mattresses
Solution Approach 1:
The bed bottom is divided into multiple independent transverse support sections (foot rest section, intermediate sections, upper body section) that can be adjusted separately. This allows the upper body section to be raised for sitting while the foot rest section remains stationary, preventing the lower body from slipping and enabling comfortable sit-up positions without moving the entire bed bottom.
Solution Approach 2:
The bed bottom sections are made dynamically adjustable through pivotable connections, allowing users to change the inclination of specific sections (particularly the upper body section) to achieve comfortable sitting positions. The sections can be positioned at different angles to suit user needs while maintaining stability.
2Ease of operation
If one bed bottom is adjusted in a twin bed, then a comfortable position is obtained for one person, but the other person lying on the other bed bottom is disturbed
Solution Approach 1:
Each bed bottom in the twin bed is equipped with independent transverse support sections that can be adjusted separately. This allows one person to adjust their side of the bed without affecting the other person's bed bottom, enabling independent comfort adjustment for each sleeper in a twin bed configuration.
3Area of stationary object
If a common mattress or mattress cover is used in a twin bed, then space is utilized efficiently, but upward adjustment of the bed bottom becomes impossible or cumbersome
Solution Approach 1:
The bed bottom is segmented into multiple transverse support sections that can be adjusted independently. This segmentation allows the bed bottom to be modified locally without affecting the entire mattress structure, enabling adjustment even when a common mattress or mattress cover is used across both bed bottoms.
Solution Approach 2:
The pivotable support sections allow dynamic adjustment of the bed bottom configuration while maintaining compatibility with common mattresses. The sections can be raised or lowered as needed without requiring separate mattresses for each bed bottom, preserving the space efficiency of common mattress usage.

AI summary
The invention relates to a bed bottom having a plurality of transverse support sections including at least a foot rest section, an upper body section and at least one intermediate section. They are adjacent to each other in longitudinal direction of the bed to support a mattress thereon in an adjustable manner. The bed bottom is adjustable from a first position wherein all support sections are substantially in line to a second position in which at least one section is moved in vertical direction. At least one intermediate section is movable downwardly from the first position to the second position. Longitudinal edges of the bed bottom for supporting the mattress remain stationary during movement of the bed bottom between the first and second positions. An adjustable headboard at the head end of the bed is adjustable between a substantially vertical position and a position in which the headboard extends obliquely downwardly from the head end of the bed towards a mattress to be supported by the bed bottom, in order to provide a comfortable support in combination with the bed bottom.
